scons: Disable the duplicate-environment warning by default.

Browse Source 
Disable warnings when targets can be built with multiple environments
but with the same actions. This can happen intentionally if, for
instance, a generated source file is used to build object files in
different ways in different environments, but generating the source
file itself is exactly the same. This can be re-enabled from the
command line if desired.
